1. In the Southern US, a white man considered to have the qualities associated with traditional conservative Southern masculine culture, including an easygoing demeanor and a generally conservative worldview. The term is applied either positively or negatively, depending on how one views such a culture. Jefferson is a good old boy—you can trust him to uphold our values. Great, just what we need—another good old boy elected to office.

2. A male who is part of a very loyal social group. Of course he only hires his friends—he's a good old boy. What do you expect? Just know that if you marry a good old boy, you're marrying his friends, too.

3. A nice, pleasant male. He's a good old boy, sure, but there's just no chemistry between us.
